I imagine this is why we saw so many Co-Op Grip Spurs and Buckshots on the back of trucks in the 70's and 80's, when fewer folks had 4wd. Just about any AT tire with some larger tread voids should clean out and grip better than a highway tire. I'd look at Cooper or Mastercraft.
Ah the old COOP GripSpur. Old guy who lets me fish used to drive a 1979 F150 4x4 Supercab longbox with those babies on all 4 corners. About 32” tall and looked like 4” wide but they’d sling the mud and it would go like hell when it was nasty out. Sorry just brought back some old memories from my childhood.
